C# - How do I access the WLAN signal strength and others?

Question

Many scientists have published papers documenting how devices connected via WLAN can be tracked by measuring its Signal Strength, Time Of Arrival, Round Trip Time, etc. Any

Answer 1

The Managed Wifi API will provide signal strength information. Here's a code snippet adapted from a question I previously posed and was answered here:

static void Main(string[] args)
{
    WlanClient client = new WlanClient();
    foreach ( WlanClient.WlanInterface wlanIface in client.Interfaces )
    {
        Wlan.WlanAvailableNetwork[] networks = wlanIface.GetAvailableNetworkList( 0 );
        foreach ( Wlan.WlanAvailableNetwork network in networks )
        {
            Console.WriteLine( "Found network with SSID {0} and Siqnal Quality {1}.", GetStringForSSID(network.dot11Ssid), network.wlanSignalQuality);
        }
    }
}

static string GetStringForSSID(Wlan.Dot11Ssid ssid)
{
    return Encoding.ASCII.GetString(ssid.SSID, 0, (int) ssid.SSIDLength);
}
